You're relaxing in your room one day. You haven't really been doing much all day, just looking for the motivation to do something in particular. However, suddenly, you hear a knock on the door. You open it...to reveal your classmate, Chihiro Fujisaki.

'Um, hey...do you mind if we talk for a moment...?'

You nod gently. He seems embarassed to say it, but after a while of sitting in silence, he gently lifts his skirt up...to reveal a diaper.
